IMPROVEMENT in BRICK-MACHINES.

Specification forming partof Letters Patent No. 173,553, dated February 15, 1876; application tiled a November 13, 1875.

Beit known that I, DAVID MANLEr, of Franklin, in the countyof 'Venan go and State of Pennsylvania, have invented a new and use.

ful lmprovement in'Brick-Machine, of which the following is a specification:

Figure 1, Sheet l, is a top view of my proved machine, parts being broken away to; show the construction.

Fig.2, Sheet l, is a rear,view ofthe same, partlyin section,through' the line a m, Fig.1. Fig. 3, Sheet 2, is a vertical section of the same, taken through the lineyy, Fig.1. Fig. 4:, Sheet 2, 'is a detail top:

view of the base-platform. Fig. 5, Sheet 2, is

a detail section of the same, taken through the line 2 2, Fig. 4. Fig. 6, Sheet 2, is a detail front view of one of the wheels and plungers.

Similar letters of reference indicate corresponding parts.

-'The object of this invention is to furnish an improved machine for molding and pressing brick, whichshall be so constructed that the three operations of filling the mold, pressing the brick, and removing the pressed brick may all be performed at thesame time, and which shall be simple in construction, convenient in use,.efl'ective in =operation, and not liable to get out of order.

The invention consists in the combination:

of the lock-bar, provided with the shoulder, the spring-latch, and the spiral spring, with the molds of the revolving platform; in the combination of the connecting-rod and the eccentric with the lock-bar -and the driving-shaft,

and in the combination of the pin and the cylindricalblock with the slotted and perforated upper end of the connecting-rod, and with the lugs formed upon. the lock-bar, as hereinafter fully described.

A is thebase-frame of the machine, to theforward part of which is secured the base-platform B. The middle part of the. platform Bis cutaway to give space for the driving-geae ing; and its rear side is slotted for the passage of the driving-shaft. In a step or socket in ends of the standards F, the lower ends of which are secured to the base-frame A. .The

connect-ionbetween the base-frameA, standards F, and cross-beam E is strengthened by long bolts, which pass through said baseformedthree holes of the exact sizeof a brick, and which are the mouths of the molds g,

formed upon or securely attached to the under side of the said plate G. side of the plate orplatform G, in the rear of the molds g, are attached or upon it is formed brackets H, to which are pivoted the rearends of the bars or blocks 1; To the lower part of the forward end of the bars or blocks I are pivoted wheels J, which roll along the base. platform B. To the upper part of the forward ends of the bars or block I are pivoted the lower ends of the. bars or plates la, the upper ends of which enter slots in the lower ends of the plungers K, and are pivoted to saidv plungers. The plungers K fit into the molds g,

and by their upward movement in said molds press the bricks against the lower side of the cross-beam. E, as indicated in Fig. 3. The plunger K is held up after pressing the brick by the way L, alongwhich the wheel J rolls. The way is attached to the platform B, extends for the third of a circle, and terminates ina doubleincline, which raises the wheel J, raising the plunger K, and forcing the brick ontof the mold, and then allows the wheel J to descend to the platform B, drawing the plunger K downward, and leaving the mold opento receive the mud. To the inner side of the double incline of the way L is attached a plate, M, the upper edge of which is'inclined, and has an outwardly-projectin g flange formed 'upon it to receive a pin attached'to the bar I,

and which may be the end of the axle of the To the under it from being drawndown by its own weight.

To the lower part of the verticalshaft Q is attached a large bmel-gear'w'heel, N,'into the teeth of which mesh the teeth of the bevelgear wheel 0, attached to the inner end of the horizontal shaft P, to the outer part of which the driving-power is applied. The inner journal of the shaft P revolves in a bearing upon a spring-bar, Q, which has sufficient strength to support the shaft Punder'ordinary circumstances; but should too much mud be put' into the mold g, the spring-bar Q will yield, and thus prevent the machine from being broken.

A portion of the teeth of the gear-wheel 0 are cut away, so as to allow the shaft P to turn through a part of its revolution without turning the gear-wheel N, but enough ,teeth are left to turn the gear-wheelN through one-third of a revolution at each revolution of the shaft P.

Upon the shaft P, directly in the path of the wheels J, is formed a cam,R, in such a position with respect to the toothless portion of the gear-wheel O that a wheel, J, shall pass upon the shaft P, the cam R shall begin to rise beneath the said wheel J, and;the gearwheel N shall be releasedfrom the teeth of the gear-wheel O at the same time, so that the platform G may stand still while the. plunger Kvis forced up by the cam R to compress the brick.

As the cam R begins to descend. the teeth of the gear-wheel N .mesh into theteeth of the gear-wheel 0, the wheel J passes from the cam R to the raised track L, and the platform G is carried forward through the third of'a .revolution. As each mold g comes into position for the biick to be pressed, the preceding mold comes over the double incline of the track L, and the pressed brick is removed, and the other or third mold comes intolposition to receive the mud, so that the threeop' erations of pressing a brick, removing aj pressed brick, and fillinga mold, are performed each time the platform Grv stops. The. platform G is stopped each time a mold, 9, comes into position for a brick to be pressed by. the

outer end of the said mold striking against a shoulder, 8 formed upon the inner side .of

the bar S, and the said platform is kept from f reboundingby a latch, 8 pivoted to the, up-

perside of the. barS, held forwardby aspring, s and. pushed back by the end; of the advancing mold.. The journals of the bar- S work.in bearings attached to the uprights F, and are made long, so that thesaid-bar S may have a short longitudinal movement in said bearings. Upon the inner part of the forward journalofthe bar S is placed a spiral spring,

8 sot-hat, as a mold, g,'strikes the shoulder 8 of the bar S, the spring 8 may yield to overcome the momentum of the platform G, and prevent the machine from being jarred or injured by the blow. The spring 8' also brings the platform G into such a position that the plungern'lay be directly over the axis of the cam while being operated, so that the segmental bevel-gear wheel will strike precisely the same place upon the three equal parts or sections of the gear-wheel. The teeth of the gear-wheel should be a multiple of three, so that the platform Gr may be turned exactly one-third of a revolution each time and the teeth of the segmental gear-wheel may engage with and release the teeth of the gear-wheel .always at the same three points.

' Upon the outer side of the middle part of the bar S are formed two lugs, 8 through which passes a pin, T, which also passes through short slots in the upper end of the connecting-bar U and through a short cylindrical block, V, inserted in a hole in the upper end of the said bar U. This connection allows the bar S to rock upon the upper end of the bar U and the lower end of the said bar U to have a lateral movement. The lower end of the bar U is connected with an cecentric, W, placed 'upon the driving-shaft P, and so arranged, in connection with the cam R, as to rockthe bar S and withdraw its shoulders s from the moldy, when the cam R begins to descend and the platform G is ready 40 move forward.

Having thus described my.invention,1 claim as newand. desire to secure by Letters Pat- -ent -1. The combination of the lock-bar S, provided with the shoulder 8 the spring-latch s 8 and the spiral spring 8 with the molds g. ofith'e revolving platform G, substantially as herein'shown and described.

2. The combination of the connecting-rod U and the eccentric W with the lock-bar S and the. driving-shaft P, substantially as herein shown and described.

3. Thecombination of the pin T and the cylindricaloblock V with the slotted andperforated upper end of the connecting-rod U, and with the-lugs s formedupon the lock-bar S, substantiallyas herein shown and described.
